Make sure the little water channels are not clogged. use a air compressor to blow those out, if they get clogged up (do you park outside near trees?) than the water has no place to go.
I have had issues with my 300ZX t-tops and I figured out the water channles were clogged, but still had a leak or two. So I got in the car and had my wife spray water at the roof with a strong hose and than we tracked down the exact source of the leak. that is something to try next.
After that find a Sun Roof specialist, there are places that only do them and know more than any stealership.
